Problem: 3D extrusions do not appear in Google Earth when using the Layer To KML tool

Description

When using the Layer To KML tool to convert extruded features in ArcScene to a KML service with 3D extruded features in Google Earth, the 3D extrusions do not appear.

Cause

This problem occurs if the polygons are in a geographic coordinate system (GCS) instead of a projected coordinate system (PCS). The polygons must be converted to a PCS before using the Layer To KML tool.

Solution or Workaround

To resolve this issue, follow the steps below.

1. Convert the features to a projected coordinate system based on the following ArcGIS Web Help topic: Exporting features.

2. Apply extrusion in ArcScene to create 3D features. To do so, follow the steps in the ArcGIS Web Help topic: Extruding features by an attribute value.

3. Create the KML file using the Layer To KML tool.
